Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Changing r.MipMapLODBias does nothing when texture samplers are set to Shared:Wrap

Changing r.MipMapLODBias does nothing when texture samplers are set to Shared:Wrap. No idea if this is intended behavior or not.

  1. Create a material that uses a texture.

  2. Assign the material to a mesh.

  3. Change r.MipMapLODBias to 5, things should get blurry everywhere.

  4. Edit the material to use a shared:wrap texture sampler. The material texture is now sharp again which doesn't make sense.

Hi, This is affecting us as well. Any chances to see it coming out of backlog? LOD Bias not affecting textures is really a big deal I'm not sure why it's backlogged.

Currently our resources are dedicated elsewhere and UE-48341 is not a priority item for us to work on. We don't have a timeframe for when this may be addressed. Please keep in mind that with source code access, a programmer on your project can implement your own solution, and you are welcome to share that result with Epic for possible integration.
